ABSTRACT:
A method and system is disclosed for providing a latent image of information on successive imaging areas of an unexposed filmstrip, so that when a picture is subsequently taken on a specific imaging area, information will appear on a portion of the picture. The foregoing is accomplished by loading a film cartridge in a camera; winding substantially the entire length of filmstrip out of the cartridge and into a film roll; metering the filmstrip one imaging area at a time off the film roll first onto a film gate optically aligned with a taking lens of a camera, and then back into the cartridge; light-projecting information through the taking lens and exposure opening to a relatively small portion of respective imaging areas at the film gate, without exposing the remainder of each imaging area, to provide a latent image of the information on each imaged area; and continuously winding the filmstrip with a latent image of the information on each imaging area, out of the cartridge and into the film roll, so that when the camera is operated to meter an imaging area to the film gate to take a picture the latent image of the information on the imaging area will be precisely located relative to the picture.
